无核葡萄品种的无核性来源分析

Analysis on Seedless Sources of Seedless Grape Breeding

系谱分析表明,无核白是世界范围内无核葡萄育种的主要无核性来源,以其为最早的亲本材料,经过简单杂交或多亲多代杂交,培育了一系列的无核葡萄品种;无核紫和俄罗斯无核是部分无核品种的原始亲本材料之一;有核葡萄的无核芽变也是无核品种选育的重要途径。

The pedigrees of main seedless grape varieties and entries bred in the world were analyzed. The results showed that Thompson Seedless was the main seedless source in seedless grape breeding. Most of seedless varieties and entries were the derivatives of the old varieties. Monukka and Russian Seedless are the seedless sources of some seedless varieties. Besides the segregation of characteristics due to sexual reproduction, natural mutation is an important sources of variation in seedless grapes.
